For a server writing files on a lot of concurrent connections, you may want
to close the file before net.Conn:Write to avoid max open file error. The
cycle is
b := make ([]byte, n)
var err error
for off:=0; err != io.Eof; off+=len {
f, err := s.OpenFile(name)
len, err := f.ReadAt(b, off)
f.Close()
Conn.Write()
}
I don't see an io package function to do this, should there be one?
